The principal parts of the machine are'arranged upon an upper and'a lower table T- and T fsupported'by suitable standards G, Figs-fiend 10. "Near the middle of the lower tabled an aperture allows thev electro-magnet E, carried by the bracket piece y, to ap-.

pear above the surface. The armature e, Figsjltl'and 11, is fixedto a shaft 0, carried in two supports 0 Fig. 11. A lever c, fixed 'to said shaft 0, is coupled with the clearinghaminer h by bars (i The h a1nme1 h-is in contactwith a spring h, serving to push the hammer back to its normal position after each forward stroke. Any excessive action of the spring is prevented by the stop-piece'e, Fig; 10, and by the set-screw e provided in the armature e. The tableT also carries asupportM,'Figs. Qand 10, provided with a sliding 'grooved plate S, having a number of re ceiving-channels ,sfor the reception of the .ltypes' as they coine down into the receiving-' cell F and are pushed out of it by the hamj mer h, Fig-11"; Upon-the upper tableTf there arefour upwardly-projecting pieces or T'ribs a and (1., Figs. 1, 9,'and 10, .of which a has as many notches as there are type-recep-. I

moles b to besupported by them. To the inner surfa'ceof the ribs a there are affixed, 7

bars D,-Figs. 1 and 10, having a dischargingcell Figs. 4, 5, 6, and 10, in front of each notch,

and these cells are each secured to-the bars 1) by one-screw m only,'Figs. 4 and 6, 50 as,to

: allow the cells it to; oscillate thereon,.as rethan by hand only. I attain this object by quired. A spring 1; pressing on the arm n,

The. cells. k are open in front of the type- "ehannelsb, placed in'the notches, and form what may be calledtheir heads.

The interior 70,; Fig; 6,.Qf j-eaohcell 7c is adapted to the size' ofthe type destined for it, but leav- "ing asufficient free space to insure-its, being readilyreleasediherefrom.

The types q, Figs. 2 and 3,arranged vertically in their inclined receptacles b,- have by their own weight, as well as by that of the triangular follower d and of the rollerld, a

tendency to glide forward and to push the foremost type on into the discharging-wills i v j and to press it against the back of thecel'l.

This tendency is," however, limited by the stops'or studs o,'Figs..4, 5, and 6, which are screwed into the bar D, soas to extend their heads into the cell is through lateral apertures.

Thus the type will bear against these studs or stops, and not against the back of the cell 4 itself.

3o ferent types required for setting. The sur' face of each key is marked with the correspending letter or sign-to that .upon which it leased y the p ator,as'wi11 be hereinafter described.

A brass bar Figs. 4, 9, and 10, is fastened.

to the bar 1) on the side opposite to the cells is, and is furnished with as many contactbufij'ers cs Figs. 4, 9, andlO, as there are table T.

type-channels b or dischargingrcells is. There is a perpendicular slit in the bar D in front of each such buffer. An insulating-layer 2,

Fig.4, (forinstance, of asbestus,) separates for carrying the horizontal electro-magnets e, .Fig. 10, arranged in duplicate pairs for more effectively operating the levers 6 while the perpendicular magnets e are secured to the The brackets e serve as centers of motion for the double levers 0 Fig. 10, which are pivoted at 6 The lower parts of said levers form the armatures, while the upper parts reach into and beyond the slits an, Figs. 4 and 5', of the bar D.. Between the rib-pieces a and a" the necessary apertures are provided in the table T','Fig. 10, for introducing the channel-board R from below the table, where it is fastened. On the table T is also the key apparatus L, Figs. 1, 8, and 9, with as many keys as there are difoperates. In the lower part of the key apparatus L an insulating-fillet 2' contains, right below each key, a contact-buffer 11,-to which the wires \V are attached by 'the'screws :0, Figs. 8 and 9. From the said screws .20 the wires pass through holes 15', Fig. 9, below the table, and are conducted thence to and through the holes 25 in the insulating-fillet i to the surface of the insulating-fillet i, where they are fixed under the screws g, Fig.:1.. Under each of these screws gis also an end of the wire of one of the electro-magnets e, and thus these latter are in communication with the keys. To prevent contact between the table'T' and the wires w. before the electric current has circulat-ed around the magnets, the wires are conducted through several insulating-fillets z",- i, 1 i i and 2' Figs. 1, 9, and 10. The other wire ends of the electro-magnets are simply fixed to the table, and this is-put in communication with the negative pole of the electric battery, which'is established under the table. All the levers e being in freecommunication with the .table '1" are consequently in connection with the same pole. The brass plate J, Figs.'S and 9, hovs'cvenwhich is in-the middle of the key apparatus L and insulated from the buffers ll, communicates with the positive pole of the same battery.

The 'wires of the elcctro-magnet E, Fig.10, are on one hand conducted to the brass bar f, Figs. 4aud 10, and on the other to the positive pole of the battery. .The channel R, Figs. 7, 9, and 10, is-composed of so many chan- *sition.

cell It is removed from its support -v and from nelss' as there are type-receptacles b,'these channels being so disposed as to converge or lead all into a central channel, and the two or more funnels are combined to form at their lower extremities .one issuing channel or throat, whence the discharged types fall into the receiving-cell F, Figs. 10 and 11, arranged upon the table below.

A sliding piece a, Fig. 10, provided with a spring it, acts as a support to the types in the grooves s, andthe screw *r, Figs. 9 and 10, serves to move the plate S and to place an empty groovein front of the cell F as soon as the preceding one is sufficiently filled.

The machine is worked in the following way, viz: W'hen acertain type is wantedfor instance, the letter A'the.key marked A is pressed down so as to effect the contact of the two fingers'cr pieces (I and d, Fig. 8, to

establish thereby the electric current. Consequently the eleotro-magnet e corresponding to the type A will be put in activity. It .will attract its armature and move the lever 8 The upper end of this lever will accordingly be lifted in the slit mand pushing aside the arm n of the cell it, Fig. 5, it will throw the said discharging-cell it out of its vertical po- By thisoscillation the type in the the studs 0. At the same time the cell it, which is placed in an oblique direction across the end of the type-receptacle b, prevents the following types from entering the cell 70 and ofpressing the first type against the back of the cell, which might impede its release therefrom. The first type is therefore completely free, and gliding from the cell 70 into the channel 5 immediately below and which forms a part of the channel-board B, it will reach the receiving-cellF, Fig. 11. As soon as the type is discharged from the cell k, which is only a moments work, the operatin g-key is let loose, th e'electric current is in terrupted, and the spring Z, Figs. 4a'nd-5, pushes the cell back into its normal position, where it is at once occupied by the following.type.-

When the'first type is in the receiving-cell F,

another'one can'be discharged by pressing the operating-key corresponding to the letter required, and so on, but apart from the effect mentioned above, another .one is obtained which will be now described, viz:

Then the upper part of thelever e is lifted in the slit m, itwill not only displace the cell 70, but alsotouch the contact-buffer X Figs. 4 and 10, and will thus communicate negative electricity to the brass bar f. The electric circuit being thus established for the electro-magnet E, this latter will be put in action at every discharge of the type. Attracting its armature, it will move the hammer h and cause the type standing in the cell F to be pushed into the groove 5 (provided in thc'sliding plate or frame S) before another type has come down.
